Researchers reported changes in brain functional connectivity after adding N-acetylcysteine to ongoing multiple sclerosis treatment, an early imaging signal that requires confirmation in larger studies with defined dosing and clinical outcomes.

Among 46 children initially at healthy weight, greater ultraprocessed food intake was associated with stronger dorsal striatal responses to appetizing food cues, which were also associated with increased adiposity measures 1 year later.

In patients with early multiple sclerosis starting interferon beta-1a, serum neurofilament light chain levels predicted progression before MRI findings were considered, but did not provide independent long-term prognostic value after adjustment for baseline imaging.

In a retrospective memory-clinic cohort, greater MRI-derived brain age was associated with dementia progression among patients with subjective cognitive decline, although its incremental predictive value was limited and external validation remains necessary.

Among 29 CPAP-adherent men with severe obstructive sleep apnea, residual objective sleepiness was associated with white-matter diffusion differences, although the cross-sectional findings do not establish causality or support routine imaging.

Baseline activity in the left dorsolateral prefrontal cortex and right precuneus during working memory and emotion-regulation tasks was associated with depression severity one year later in young adults at elevated risk for affective disorders, but not with future mania symptoms.
